Topographic Map Tricks

Trick #1 Contour Lines can never cross or intersect.

Trick #2 Lines close together = ____Steep______ Lines far apart = ____Gentle______

Gentle vs. Steep

Trick #3 Rivers make “V” shapes, but PACMAN must go down in NUMBER!

____________ = Mountian Peaks Trick #4 ____________ = Mountian Peaks

____________ = Depressions Trick #4 ____________ = Depressions - volcanoes - lakes - craters

Contour Interval = Distance between each line Trick #5 Contour Interval = Distance between each line HOW TO CALCULATE…? Take two numbers and Subtract Take the difference and divide by number of lines. That is your contour interval!

What is the contour interval? Answer 20
